The XSLA-081019-RH is a high-performance X-band antenna engineered for space, airborne, and mission-critical datalink applications requiring high gain, excellent polarization purity, and robust power handling. Operating across the 7.8–8.2 GHz band, the antenna delivers 19.0 dBic gain, a 17° typical 3-dB beamwidth, and right-hand circular polarization (RHCP) in a compact, mechanically rugged package.
Designed for satellite Telemetry, Tracking & Command (TT&C), high-rate downlinks, and precision point-to-point links, the XSLA-081019-RH supports up to 50 W CW input power, enabling increased system EIRP and improved link margin compared to conventional low-power X-band solutions. Its low axial ratio (< 1.75) and controlled sidelobe levels (–12 dB typical) ensure stable polarization performance and reduced interference in dense RF environments.
The antenna is well suited for CubeSat and small-satellite platforms, airborne ISR systems, and other space-constrained applications where reliable X-band communications and repeatable performance are required.
